I SPECIFICATION formingpart of Letters Patent No. 665,226, dated January 1, 1901.

' Application filed ()ctober 17,1900. eel-mi o. 33,331. (No model.)

To all whom it may concern: I

Be it known that I, EDWARD A. JOHNSTON, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in HorseHay-Rakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to the construction of the head of the rake and the manner of securing the teeth in place; and the particular objects in view are to economize in the amount of material and the cost of manufacturing the head and to dispense with the use of bolts,

nuts, and other fastenings for securing the teeth to the head.

The invention will be readily understood from the following description, taken in connection with the accompanying drawing, forming part of this specification, wherein a fragment of the head of an ordinary h0rse-.

tervals along this head are the teeth B, which,

except at their upper ends and in the manner of securing them to the head, may be of any preferred forin'and construction. With a view to making these teeth self-securing, and thereby to dispense with the use of the bolts, nuts, or other fastenings which have heretofore usually been employed, the horizontal flange of the head is provided near its front edge with slots or holes I) and the vertical flange has corresponding slots or holes I) near its lower edge.

The teeth,which are preferably constructed of wire, are wound at their upper ends into a coil 0, and the extremity of the wire projects upward from one sideof this coil, as at (3!, while the inain portion ofthe wire, forming the teeth proper, projects horizontally toward the rear, as shown at d, and passes through the vertical slot 1) in the flange a. The upper end of the portion 0' of the wire projects into the slot bin the horizontal flange of the head, and the resilience of the coil pressing the end 0' against the front part of the slot b and the part gl against the lower end of the slot 1/ holds the teeth firmly and securely in place.

As will be understood from the drawing, the vertical flange a depends from the rear edge of the rake-head, and the upstanding end 0' of the wire being on the front side of the coil and the horizontal part 61 being 0n the lower side of the coil'the coil itself is inclosed, housed, and protected in and by the angularspace between the flanges. Thus the reaction of the coil causes the two portions of the wire to press in the planes of the respective flanges of the head-that isto say, in

planes, at right angles to each other, the onehorizontal and the other vertical -and the teeth are secured and held in place entirely by their own resilience, all separate fastenvings being dispensed with.

The perforations b b are herein shown as elongated slots. Itis not essential, however, that they should be anything more than holes;

but in order to allow the body portions of the teeth the proper range of movement it is deemed specially advisable to elongate the holes I), and thus allow for the desired verpresses the rear side of the coil against the front face of the flange a and the reaction of the part (1 presses the upper side of the coil against the under surface of the horizontal flange.

Having thus described inyinvention, what I claim and desire to secure is 1. The combination with a rake-head formedof angle-iron, of a wire tooth having a coil at its upper end, the extremity of the wire on one side of the coil engaging the horizontal flange of the head, and the wire on the opposite side of the 'coil passingthrough the verits upper end the extremity of the wire onone side of the coil engaging a slot or perforation in the horizontal flange of the head,

1c and the portion of the wire on the opposite side of the coil passing through a slot or perforation in the vertical flange of the head, the tooth beingheld to the head by the resilience of the wire reacting in the planes of the flanges.

3. The combination with a rake-head formed of angle-iron having horizontal and vertical flanges, of a wire toothhavin'g a coil at its upper end inclosed within the flanges, the

wire on the opposite sides of the coil engaging slots or perforations in the respective flanges, and the resilience of the Wire reacting in the planes of the flanges to hold the tooth to the head.

4. The combination with a rake-head formed of angle-iron having vertical and horizontal flanges, of a wire tooth having its upper end passed through a slot or perforation near the lower edge of the vertical flange and wound into a coil inclosed in the angle between the flanges and having its extremity extended upward through a slot or perforation in the horizontal flange. I

In testimony whereof I aflix my signature in presence of two witnesses.

EDWARD A. JOHNSTON.
